ecosystem : the complex of a community of organisms and its environment functioning as an ecological unit — Webster
Ecosystem is a community made up of living organisms and nonliving components such as air, water, and mineral soil. Ecosystems can be studied in two different ways. They can be thought of as interdependent collections of plants and animals, or as structured systems and communities governed by general rules. The living (biotic) and non-living (abiotic) components interact through nutrient cycles and energy flows. Ecosystems include interactions among organisms, and between organisms and their environment. Ecosystems can be of any size but each ecosystem has a specific, limited space. — Wikipedia
Biome is a community of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents. Biomes are distinct biological communities that have formed in response to a shared physical climate. “Biome” is a broader term than “habitat”; any biome can comprise a variety of habitats.
A ‘biota’ is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. — Wikipedia
Ecology is the branch of biology which studies the interactions among organisms and their environment. Objects of study include interactions of organisms with each other and with abiotic components of their environment. Topics of interest include the biodiversity, distribution, biomass, and populations of organisms, as well as cooperation and competition within and between species. Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and niche construction, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits. — Wikipedia

Scientists on Earth will soon see our planet's atmospheric dust sources in high resolution, as a new state-of-the-art imaging spectrometer—developed by NASA's Jet Propulsion Laboratory (JPL) and Cornell University—aims to survey the land surface from 250 miles above us on the orbiting International Space Station.
- Environment scientists close in on 'golden spike'...on May 19, 2022 at 7:46 pm
Leicester researchers searching for a "golden spike" to formally define humanity's current geological period—and acknowledge human impact on our planet—have announced a major step in their analysis at an international conference on Wednesday.

How will future warming of the planet impact cold-water corals? A new analysis of ancient evidence from the last major global warming event identifies food and oxygen supply as key environmental factors that influence the vitality of cold-water corals in the North Atlantic Ocean and the Mediterranean Sea. Rodrigo da Costa Portilho-Ramos of the University of Bremen, Germany, and colleagues present these findings in the open-access journal PLOS Biology on May 19.

Researchers have discovered new clues to understand how killer whales impact their environment.
- Satellite monitoring of biodiversity moves within...on May 19, 2022 at 12:11 pm
Global biodiversity assessments require the collection of data on changes in plant biodiversity on an ongoing basis. Researchers have now shown that plant communities can be reliably monitored using imaging spectroscopy, which in the future will be possible via satellite. This paves the way for near real-time global biodiversity monitoring.
- For wetland plants, sea-level rise stamps out...on May 18, 2022 at 6:07 pm
Wetlands across the globe are in danger of drowning from rising seas. But for decades, scientists held out hope that another aspect of climate change -- rising carbon dioxide (CO2) -- could trigger extra plant growth, enabling coastal wetlands to grow fast enough to outpace sea-level rise. That helpful side effect is disappearing, scientists have discovered.
